Pandorical

Updated to 26.3-snapshot-10.

Inventory & screens:

• Mods can put buttons (and toggle switches) on the player's own inventory screen
• Extra inventory slots survive death instead of quietly ceasing to exist
• Container screens never trim oversized stacks the server sent (trade screen included)
• Containers can refuse items the way vanilla does, get open/close notifications, and match the server's slot count and vanilla geometry
• Screen teardown no longer erases the screen replacing it

Server-side mod support:

• A mod's vanilla-namespace assets now reach the client
• A mod can claim a vanilla block's right-click by naming it, and let a server-only block be climbed
• Synced tools and worn armour present correctly on the client
• Version handshake fixes: config-phase acks land on the server thread exactly once, and the client actually listens for the version check

Map & HUD:

• Vanilla draws the player marker; an optional heading arrow sits in the corner
• Map coordinates are clamped against bad wire data
• A real top_center HUD anchor
